A stackable wear panel (1) for use within a modular stackable wear-resistant panel system (11) is configured to be removably affixed to a wall (10A) or surface of equipment (10) to be protected. The stackable wear panel (1) is also configured to be alternatively removably affixed to a top surface (2A) of another stackable wear panel (1) within a stacked wear panel arrangement (1′, 1″). The stackable wear panel (1) is formed by a matrix (2) having a top surface (2A), a bottom surface (2B) opposite said top surface (2) and a central bore (4) extending through the top (2A) and bottom (2B) surfaces. The central bore (4) is configured to receive either one of a fastener (5) or a spacing adapter (6) therein, and/or support a portion (5A, 5B) of the fastener (5) or a lower outer surface portion (6E) of the spacing adapter (6).
